you want to improve your sexual performance and go on wikipedia or some other site to read about the layout and science about the genitalia of your and your partners.
Go ahead, make your own. Perhaps this is a bit more suited to the sex & relationship forums. Do not let them know :D
Yes, I may be jumping the bandwagon of "piss off" threads, but I'm alright with that.
INTJ's, what pisses you off? What irks you?
Everyone else, what do you say upsets the INTJ?
Everything. I can piss and moan under any circumstance; but it's this that leads to improvement.
